Y=5 x 3 to the power of 4 help asap

405

Step-by-step explanation:

First you do the exponent first which would be 3 to the power of 4 which is 81 and then you would multiply that by 5 which gives you 405.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3
